1.4 Mountings for the load The autoclave is delivered with a mounting rack. The space inside the mounting rack is the space that can be

sterilized effectively. Hence the rack must be used while loading the autoclave. The mounting rack can hold 3 trays.

Figure 1.5 Mountings of load

1.5 Intelligent controller and the control panel The controller is the core of the autoclave. It not only accomplishes real-time parameters acquisition,

processing, fault detection and control of a sterilization process, but also accurately depicts the graph of temperature

and pressure that change over time. The controller is also responsible for the assessment and monitoring of the

program control process. During the sterilization period, it will compare the running parameter with the standard

parameter, once the running parameter deviates from the standard, it will generate fault messages immediately, and

ensure the safety and quality of the sterilization.

The system offers convenient and simple operation through a colored 3.5 inch display and a jog-dial knob.

1.5.1 The control panels

In the control panels, system status bar is on the top and displays time, task, door lock status and external

storage device status. The main interface in the middle displays different contents depending on various tasks or

1.7 Program sequences 1.7.1 Regular sterilization program

A program runs in 3 phases, air removal, sterilization and drying phase. After program starts, the user can

follow the program running status on the display. It shows the chamber temperature and pressure as well as time

elapsed for the current running program.

Program Phase Description

1.Air removal

The air removal phase comprises the conditioning and the evacuation. During

conditioning, steam is repeatedly injected into the sterilization chamber to

generate over-pressure. During evacuation, the mixture of air and steam is

then removed repeatedly. This procedure is also called the fractionated pre-

vacuum procedure. Number of pre-vacuum fraction varies from program to

program. GEN134 is set for 3 times of pre-vacuum fraction and Helix or 134+

is set for 4 times.

2.Heating

The heating phase follows the air removal phase. Steam continuously entering

into the chamber leads to an increase in pressure and temperature until the

program-specific sterilization parameters are reached.

3.Sterilization

Sterilization phase begins when pressure and temperature match the pre-set

nominal values. Sterilization phase ends when pressure and temperature are

maintained for a period of time that is program-specific.

4.Pressure release After sterilization phase, pressure releases by evacuating steam from

chamber.

5.Drying Drying phase begins after pressure release. The load is dried using a vacuum.

During drying the air filter ensures sterile environment in the autoclave.

6.Ventilation Ventilation happens during drying phase. Upon program end, the chamber

pressure is adapted to the ambient pressure.

1.7.2 Vacuum test

The purpose of vacuum test is to measure the leakage rate of the autoclave. No sterilization is performed during

vacuum test. Please run vacuum test with a cold, dry and empty autoclave.

Program phase Description

1.Air removal Air is evacuated until the pressure in the chamber reaches the pre-set value.

2.Equilibration An equilibration time of 5 minutes.

3.Measurement Measurement time of 10 minutes during which pressure in the chamber is

monitored and displayed.

4.Test end The screen shows the test result: leakage rate

get wet or scorched. Please use the original mounting rack and trays that have ventilation holes at the base.

Proper loading is the key to effective sterilization and good drying

results. The below instructions must be followed carefully to load the

autoclave properly:

Only use packaging materials and systems which meet EN 868

standard;

While sterilizing instruments wrapped in plastic paper pouches, the

paper side must be facing upward;

While sterilizing mixed loads, always place textiles at the top;

Leave sufficient room between pouches;

The total loaded space should not exceed 90% of the chamber

space.

4.4 Running the cycle 4.4.1 Start the cycle

After entering the program introduction interface (Fig. 4.2), rotate the jog-dial to【Start】and press to

confirm. The autoclave will check the door lock status and water quality before running the selected program.

4.4.2 Program execution

A program runs in 3 phases, the air removal phase, sterilization and drying. Please refer to Section 1.6.1 of

this User Manual for explanation of each phase. The screen displays real-time chamber temperature and pressure

as well as time information of the cycle, as shown in Fig. 4.3.

Figure 4.3 Program execution

4.5 Manual program abort A program can be aborted in all phases. If program ends before drying begins, the sterilization load is

unsterile. Otherwise, the items have been sterilized but not sufficiently dried. In full load case, it is highly possible

for wet pack to occur. These wet packs cannot be stored because sterile storage set high requirements on the level

of dryness.

Hot steam can be released from the autoclave when opening the

door after a program abort. This could result in burns!

Never touch the sterilized instruments, the chamber or the door

with bare hands. These components are hot!

Always use a tray handle or proximity gloves to remove the trays.

Danger of infection from early program abort!

Aborting a program before the drying phase begins means that the

load is unsterile. This endangers the health of your patients and

the operator;

If necessary, repack the load and repeat the sterilization.

- 19 -

If manual abort is necessary, rotate the jog-dial and press 【Stop】in the screen (Fig. 4.4 left). After the

program is manually aborted, the screen prompts error messages and displays program ending interface (Fig. 4.4

right). The intelligent controller keeps monitoring temperature and pressure in the chamber and status of other

components of the device. The controller will only allow the user to open the door when it is safe to do so.

Usually it takes a few minutes for the device to reach the stage.

4.6 Program complete After a program runs successfully to the end, the screen displays program complete interface and program

success message (Fig. 4.5). If automatic printing is set and the printer is connected correctly, the autoclave will

print the sterilization record automatically. Rotate the jog-dial to 【Open】icon and press it to open the door.

Figure 4.5 Program complete

Danger of burns from hot surfaces and hot steam!

Never use force to open the door. This could damage the device

and /or result in the emission of hot steam;

Allow the autoclave to cool sufficiently before opening;

Figure 4.4 Manual abort

Stop Open

- 20 -

Do no touch any hot metal parts;

Never touch the sterilized instruments, the chamber or the door

with bare hands.

Always use a tray handle or proximity gloves to remove the trays. Hold the mount level when removing it from the chamber.

Otherwise, the load could slide off.

Damaged or burst packaging lead to unsterile instruments. This

endangers the health of patients and operators.

Should the packaging be damaged or have burst, re-pack and re-

sterilize the items.

Leaving the sterilized items in the chamber for 5 min after the

program completes is beneficial for dryness of the sterile packs;

According to the AKI (red brochure 10. Edition; S.57), residual

moisture in the form of a few drops of water capable of evaporating

within 15 min is tolerated, but actual pools of water are not

acceptable.

It is recommended to keep records of every cycle for further

reference. In some countries, it is mandatory to do so.

4.7 Storing sterile instruments

The maximum storage time is dependent on the packaging and the storage conditions. For standard-conform

packaged sterilized instruments, if protected from dust, it can amount to up to six months. Comply with the

provisions of DIN 58953, part 8 and the criteria specified below for the storage of sterilized instruments.

Comply with the maximum storage duration in accordance with the

packaging type;

Do not store the sterilized instruments in the decontamination area;

Store the sterilized instruments in dustproof, dry (free from moisture,

alcohol, disinfectant etc), temperature controlled environment.
